| description | A pump assembly including a pump attachment adapted to form a nonaerosol pump sprayer, and a method of using the same. The apparatus includes an attachment having a pump sprayer that is pressurized on the upstroke. The attachment includes a body that defines a chamber, a shaft moveable between a first and second position in the body, a piston, a first valve and a second valve. The first valve permits the flow of fluid into the chamber and restricts the flow of fluid out of the chamber. The second valve moves between an open position-permitting the flow out of the chamber and a biased closed position restricting the flow out of the chamber. When the shaft is moved to the first position, the shafts moves the second valve from the closed position to the open position. An apparatus with a bleeder orifice for automatically releasing pressure is also disclosed. |
